H1 FF Device Configuration and Commissioning
Fieldbus devices require far more attention in their initial setup and commissioning than their analog counterparts. Unlike an analog transmitter, for example, where the only “configuration” settings are its zero…
Practical Calibration Standards
As previously defined, calibration refers to the checking and adjustment of an instrument so that its output faithfully corresponds to its input throughout a specified range. In order to calibrate…
How to Stop Cyber Attacks on PLC or DCS?
As control system professionals, it is in our interest to ensure our measurement and control systems are secure from unauthorized access. It is helpful to regard system security similarly to…
Unbonded Strain Gauge Principle
These strain gauges are not directly bonded onto the surface of the structure under study. Hence they are termed as unbounded strain gauges. Description of the Unbonded Strain gauges: The arrangement of an unbonded strain gauges…
Semi Conductor or Piezo Resistive Strain Gauge Principle
These gauges are directly bonded (that is pasted) on the surface of the structure under study. Hence they are termed as bonded strain gauges. The three types of bonded strain…
Metal Foil Strain Gauge Principle
These gauges are directly bonded (that is pasted) on the surface of the structure under study. Hence they are termed as bonded strain gauges. The three types of bonded strain…
Fine Wire Strain Gauge Principle
These gauges are directly bonded (that is pasted) on the surface of the structure under study. Hence they are termed as bonded strain gauges. The three types of bonded strain…
Sling Psychrometer Principle
Sling Psychrometer is used to measure both the dry bulb and wet bulb temperatures at time. These temperatures are a measure of humidity content in air. Description of Sling Psychrometer…
Humidity Sensing Absorption Hydrometer Principle
A change in resistance with change in humidity is taken as a measure of humidity. This is type of Electrical Humidity sensing Absorption Hydrometer, know more about mechanical humidity sensing…
Hair Hydrometer Principle
Due to humidity, several materials experience a change in physical, chemical and electrical properties. This property is used in transducer that are designed and calibrated to read relative humidity directly. Hair…
